A portable computer includes a base unit having a keyboard and a display unit rotatably coupled to the base unit. The display unit is rotatable between a closed position where the keyboard is covered and an open position where the keyboard is exposed. A latch member is provided on the externally exposed area of the display unit and latched to an externally exposed area of the base unit when the display unit is rotated to a closed position. The latch member is so mounted on the display unit as to be rotated toward and away from the display unit. The latch member is normally urged in a direction to rotate into engagement with the base unit under an action of a latching spring. The latching spring maintains the latch member in an engaged relation to the base unit when the display unit is rotated to the closed position.
